hw/openrisc: Support monitor dumpdtb command
The openrisc machines don't set MachineState::fdt to point to their
DTB blob. This means that although the command line '-machine
dumpdtb=file.dtb' option works, the equivalent QMP and HMP monitor
commands do not, but instead produce the error "This machine doesn't
have a FDT".
Set MachineState::fdt in openrisc_load_fdt(), when we write it to
guest memory.
